    Auto headlights stay on all the time

    Anyone else had this issue? My lights seem to be on all the time. I just replaced both bi-xenons with new AL ones. I'm not sure if the problem existed before I replaced the headlights though... It may have been like this for a while and I just noticed it...

    Where is the light sensor anyhow?

    Its in with the rain sensor. Do you rain sensing wipers work? If the fuse that is responsible for both of these is blown or removed, u have adjustable speed wipers, but ur lights wont work on auto. They will just turn on. I removed this fuse cause my rain sensor is shot, and I wanted intermittent wipers at least.

    there should be extra fuses in the fuse box, just try changing the one that controls the sensor

    Havnt had a chance to check the fuse yet, but it appears they are now working. I wonder if there is something blocking the sensor. Where is the actual sensor that detects if it si dark out?

    It's the lil hole, right below the headlight switch.

    Ohh... inside the car--so shadows can determine if the lights are on etc. I bet that was the issue

    Perhaps....

    Don't know for sure....but shouldn't headlights go out after a pre-determined time, with the engine not running?

    No, it's the one on the rear view mirror mount. I can make mine turn on if I put my hand over it

    Not sure. There is also that little sensor on the back of the mirror itself that I'm not sure what it does
